•
Administrator: a person who is responsible for managing a multi-user computing environment, such as a
local area network (LAN). The responsibilities of the system administrator typically include: installing
and configuring system hardware and software; establishing and managing user accounts; upgrading
software; and backup and recovery tasks.
•
Alias: a fictitious name
•
Client/Server: describes the relationship between two computer programs in which one program, the
client, makes a service request from another program, the server, which fulfills the request.
•
Console: the text entry and display device for system administration messages, particularly those from
the BIOS or boot loader, the kernel, the
•
DHCP: (Dynamic Host Configuration Protocol) is a communications protocol that lets network
administrators centrally manage and automate the assignment of Internet Protocol (IP) addresses in an
organization's network. Without DHCP, the IP address must be entered manually at each computer in an
organization and a new IP address must be entered each time a computer moves to a new location on the
network.
•
Download: the transmission of a file from one computer system to another.
•
Ethernet: the most widely-installed local area network (LAN) technology - specified in a standard, IEEE
802.3.
•
Firewall: a set of related programs (located at a network gateway server) that protect the resources of a
private network from users on other networks and control what outside resources its own users have
access to. (The term also implies the security policy that is used with the programs.)
•
Gateway: a network point that acts as an entrance to another network. On the Internet, a node or
stopping point can be either a gateway node or a host (end-point) node.
•
Host Computer: a computer in which the NCT-2000-XP program has been installed
•
Internet: a worldwide system of computer networks in which users at any one computer can, if they have
permission, get information from any other computer (and sometimes talk directly to users at other
computers).
•
IP Address: the Internet Protocol (IP) is basically the set of rules for one network communicating with
any other (or occasionally, for broadcast messages, all other networks). Each network must know its
own address on the Internet and that of any other networks with which it communicates. To be part of
the Internet, an organization needs an Internet network number, which it can request from the Network
Information Center (NIC). This unique network number is included in any packet sent out of the
network onto the Internet.
•
LAN: local area network (LAN) is a group of computers and associated devices that share a common
communications line or wireless link and typically share the resources of a single processor or server
within a small geographic area (for example, within an office building). Usually, the server has
applications and data storage that are shared in common by multiple computer users. A local area
network may serve as few as two or three users (for example, in a home network) or as many as
thousands of users (for example, in an FDDI network).
•
Log on: in general computer usage, logon is the procedure used to get access to an operating system or
application. Almost always, a logon requires that the user have (1) a user ID and (2) a password. Often,
the user ID must conform to a limited length such as eight characters and the password must contain at
least one digit and not match a natural language word
•
MAC Address: in a LAN or other network, the MAC (Media Access Control) address is your computer's
unique hardware number. (On an Ethernet LAN, it's the same as your Ethernet address.) When you're
connected to the Internet from your computer, a correspondence table relates your IP address to your
computer's physical (MAC) address on the LAN.
